Management of Macrophomina phaseolina (Tassi.) Goid. Causing Leaf Blight Disease in Mung Bean in Maharashtra State

Abstract

Leaf blight (LB) disease caused by Macrophomina phaseolina, an important constraint in mung bean production in India. In the present investigations, the aimed to evaluate the loss in yield, better mung bean cultivars against LB and the efficient management. Based on symptomatology, cultural and morphological characteristics the pathogen isolated from cv JL-781 it was identified as M. phaseolina (Tassi.) Goid. inducing LB disease. Pathogenicity of M. phaseolina was proved on the mung bean cv JL-781. Subsequently, field experiment was conducted for the management of LB disease using seed treatment with carbendazim 50 WP a.i. 0.2% (2 g/kg) + spraying of zinc sulphate monohydrate @ 0.01% + soil application of Trichoderma viride @ 5 g/ha mixed with 3 kg of FYM + foliar spray of garlic extract (10%) showed 15.45% incidence. This result was followed by 16.79% disease incidence and 15.44% disease severity by seed treatment with carbendazim, foliar spray of zinc sulphate, and soil application with T. viride @ 5 g/ha mixed with 3 kg of FYM.
